论文摘要
可编程无线环境（PWES）利用电磁元信息将无线传播转换为软件控制的资源。在这项工作中，我们研究用户设备移动性对PWE效率的影响。提出了一个分析模型，该模型描述了用户发射波和主动PWE配置之间的潜在未对准，并且可以构成研究PWE中排队问题的基础。随后，提出了一种新颖的梁转向方法，可以有效地减轻未对准效果。基于射线追踪的模拟评估了所提出的方案。
Programmable wireless environments (PWEs) utilize electromagnetic metasurfaces to transform wireless propagation into a software-controlled resource. In this work we study the effects of user device mobility on the efficiency of PWEs. An analytical model is proposed, which describes the potential misalignment between user-emitted waves and the active PWE configuration, and can constitute the basis for studying queuing problems in PWEs. Subsequently, a novel, beam steering approach is proposed which can effectively mitigate the misalignment effects. Ray-tracing-based simulations evaluate the proposed scheme.
